| A doc opens at once: the page carries the document's saved state, so the editor mounts without waiting for its live room, which connects in the background and sends only what changed, with a quiet dot that turns green when it's synced; edits made before then are kept and sent once. The editor's code is preloaded from the page and fetched early when you hover a doc, the app's shared code ships in a few chunks instead of a hundred small ones, socket tickets come with the page instead of a round trip, and the artifacts service answers a page, a sidebar and a room in parallel lookups instead of a dozen in a row, reporting its database round trips in Server-Timing. The artifacts guide says how a doc opens, and CONTRIBUTING's Speed section has the numbers. | 5 | import { getViewer, roleIn } from "./session.server"; |

| Chat is the phone app's first part, in full and live, with notifications on the phone. Conversations draw messages as the site does, from the same Markdown parser, run one author's messages together and mark the days; new messages, edits, deletions, reactions and typing arrive over the conversation's socket, and what you send shows at once and can be sent again if it fails. Agents' cards work: their buttons act from the phone, asking first or for an amount when the card does. Long-press a message to react, reply in a thread, copy it, or edit or delete your own; threads open with the message they are under; a conversation can be starred, muted or left; New message messages people and agents or makes a channel, and Browse joins channels. While the app is in front it keeps the person's feed open as a tab does: unread counts move on the list and the Chat tab, notifications show as a banner unless that conversation is open, and DMs show who is online. The bar is the site's phone bar: Home, Notifications and Agents say they are coming and open the site, and Customize and the account move under More. | 8 | import { bearerToken, socketUser } from "./website-token"; |
